우리나라의 수량에 큰 영향을 미치는 요인을 구명하기 위해콩의 주요 생산지인 파주, 안동 및 무안의 3지역에서 2012년도에서 2014년까지 3개년의 설문 및 현지조사의 자료를 분석한 결과는 다음과 같다.
1. 3지역 3년 전체 중회귀분석 결과를 보면 비닐피복을 하면 ha당 488 kg (23%) 증수를 하였고 논재배가 밭재배 대비ha당 520 kg (24%) 증수를 하였으며 추가관수 1회마다(3회까지) ha당 165 kg씩(7%정도) 증수를 보였다.
2. 수량에 큰 영향을 미치는 저수요인은 지역별 기상조건에 따라 달라지지만 무안, 안동 파주 등 3지역을 3년간 조사한 결과를 대상으로 분석하면 콩의 수량 감수 주요인은 6월과9월의 토양수분 부족이었다.
Currently cultivation area of soybean and percentage of self-sufficiency has been decreasing in Korea. The trend of soybean yield in farm is at a standstill. The difference of soybean yield between farm is large and soybean yield is low compared to the potential yield. During that time, to obtain a high yield in soybean many researchs focused on imputing cultivation techniques. A research for factors affecting to soybean yield through comprehensive analysis of actual condition in soybean cultivation have not practiced in our country. Accordingly, this research was carried out to investigate factors affecting to soybean yield based on actual condition of farmer’s field. This research was performed at three major soybean producing districts, Paju, Andong and Muan from 2013 to 2014. The soybean cultivar Daewon was grown in Paju and Andong, and the other cultivar Taekwang in Muan. Survey was conducted in 2013 for soybean cultivation factors in 2012, and the investigation in 2014 was practiced for survey on cultivation factors in 2013 along with field investigation. The contents of questions and field investigation were seeding dates, planting distances, frequency of fungicide and pesticide treatment, degree of weed occurrence, P.E. film mulching or non mulching, amount of fertilizer application, irrigation frequency, paddy or upland field and soybean yields in this study. Investigation factors were analyzed using multiple regression model of SAS program. The results of multiple regression analysis in three districts for three years are described follows: soybean yield increased by 488kg/ha(23%) under P.E. film mulching, 520kg/ha(24%) in paddy field cultivation, and 165kg/ha(7%)/10a per supplement irrigation to three times. Based on above results, even though factors affecting to soybean yield differs under weather condition in each district, major factor of soybean yield decrease was shortage of soil moisture during June and September according to the investigated data at three districts during three years in this research.
